You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer … WebAs mentioned earlier in the preparation reactions, thiols and especially thiolates are great nucleophiles. At the same time, the larger size of the sulfur makes it a weaker base than, for example, oxygen. Remember, alkoxide ions are good nucleophiles and also strong bases and when reacted with bulkier substrates, the E2 reaction starts dominating.
